The product is High Quality Fluorescent Brightener 378 / Optical brightener CBS - 127 with the CAS number 40470 - 68 - 6. It comes with the Best Price. Fluorescent brighteners are chemical compounds that absorb light in the ultraviolet and violet region (usually 340 - 380 nm) of the electromagnetic spectrum, and re - emit light in the blue region (usually 420 - 470 nm). This process is known as fluorescence. The high - quality of this fluorescent brightener implies its superior performance in terms of brightness enhancement, stability, and compatibility with various substrates.
Regarding its physical and chemical properties, it typically exists in a powder form, which makes it easy to handle and mix with other substances. It has good solubility in certain organic solvents, which is an important factor for its application in different industries.
1. **Textile Industry**: In the textile industry, this fluorescent brightener is widely used to enhance the whiteness and brightness of fabrics. It can be applied to natural fibers such as cotton, wool, and silk, as well as synthetic fibers like polyester and nylon. By treating the fabrics with this brightener, they can achieve a more appealing appearance, making them look cleaner, newer, and more vivid.
2. **Paper Industry**: In paper manufacturing, it helps to improve the optical properties of paper. It can make the paper appear whiter and brighter, which is especially important for high - quality printing papers, magazines, and packaging materials. The brightened paper not only looks more attractive but also provides better readability and visual impact.
3. **Detergent Industry**: Fluorescent brighteners are often added to detergents. When used in laundry detergents, they attach to the fabric fibers during the washing process. As the fabric is exposed to light, the brightener absorbs ultraviolet light and re - emits blue light, which counteracts the yellowing effect that fabrics may develop over time, making the clothes look brighter and cleaner.
The usage of this fluorescent brightener depends on the specific application and the substrate it is used on. For textile applications, it can be applied through a padding process. First, prepare a solution of the brightener with an appropriate concentration in water or a suitable solvent. Then, immerse the fabric in the solution, and pass it through a padder to ensure uniform distribution of the brightener on the fabric. Finally, dry the fabric at an appropriate temperature.
In the paper industry, it can be added to the pulp during the papermaking process. The recommended dosage is usually determined based on the desired brightness level of the paper. It should be thoroughly mixed with the pulp to ensure even distribution throughout the paper.
For detergent products, it is simply added during the manufacturing process of the detergent formulation. The exact amount depends on the type of detergent and the target performance.
1. **Textile Manufacturer A**: A textile manufacturer that produces high - end cotton shirts was facing the problem of dull - looking shirts after washing. They decided to use our High Quality Fluorescent Brightener 378. By applying it through the padding process, the shirts became significantly brighter and whiter. Customers noticed the difference immediately, and the sales of the shirts increased by 20% within a month. The brightener also showed good fastness properties, ensuring that the brightness was maintained after multiple washes.
2. **Paper Mill B**: A paper mill producing premium printing papers was striving to improve the brightness of their products to meet the high - end market requirements. After adding our fluorescent brightener to the pulp, the paper's brightness increased by 10% on the ISO brightness scale. This improvement made the printed materials on their paper stand out, attracting more high - end clients, such as luxury brand magazines and high - end book publishers.
3. **Detergent Company C**: A detergent company was looking to enhance the performance of their laundry detergent. They added our brightener to their formulation. In consumer tests, the detergents with the brightener were perceived as more effective in making clothes look cleaner and brighter compared to their previous products. As a result, the market share of their detergent increased by 15%.
